FIELD OF THE INVENTION

Embodiments of the present invention comprise methods and systems for imaging device accounting and in particular, concurrent use of an account by multiple users.

BACKGROUND

Imaging devices such as printers, copiers, scanners and fax machines can have a wide array of functions and capabilities to fit specific uses or combinations of uses. Imaging devices often take the form of a multi-function peripheral device (MFP) that combines the functions of two or more of the traditionally separated imaging devices. An MFP may combine any number of imaging devices, but typically comprises the functions of a printer, scanner, copier and fax machine.

Some imaging devices may contain computing resources for data storage and processing such as processors, hard disk drives, memory and other devices. As imaging devices add more features and functions, they become more costly and complex.

More complex imaging devices and MFPs may comprise network connectivity to provide communication with other computing devices, such as personal computers, other imaging devices, network servers and other apparatus. This connectivity allows the imaging device to utilize off-board resources that are available on a connected network.

Imaging devices typically have a user input panel with an array of buttons, knobs and other user input devices. Some devices also have a display panel, which can be for display only or can be a touch panel display that enables user input directly on the display.

Devices with touch panel displays or displays with buttons arranged in cooperation with the display can display menu data that may be selected by user input. This menu data is typically driven by an on-board server module within the imaging device.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Embodiments of the present invention will be best understood by reference to the drawings, wherein like parts are designated by like numerals throughout. The figures listed above are expressly incorporated as part of this detailed description.

It will be readily understood that the components of the present invention, as generally described and illustrated in the figures herein, could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of the embodiments of the methods and systems of the present invention is not intended to limit the scope of the invention but it is merely representative of the presently preferred embodiments of the invention.

Elements of embodiments of the present invention may be embodied in hardware, firmware and/or software. While exemplary embodiments revealed herein may only describe one of these forms, it is to be understood that one skilled in the art would be able to effectuate these elements in any of these forms while resting within the scope of the present invention.

Embodiments of the present invention comprise interfaces and architecture that integrate imaging devices with remote computing device applications and environments to provide solutions that may not be possible solely with an imaging device alone. Some embodiments comprise an infrastructure and set of interfaces that allow applications on a network to programmatically control imaging device functions and interact with a user through an imaging device input panel. Software functions that are not practical within the imaging device can be performed on the server but are accessible from the imaging device.

For the purposes of this specification and claims, an imaging device (IDev) may be described as a device that performs an imaging function. Imaging functions comprise scanning, printing, copying, image transmission (sending and receiving), image conversion and other functions. Exemplary imaging devices comprise printers, copiers, facsimile machines, scanners, computing devices that transmit, convert or process images and other devices. An IDev may also perform multiple imaging functions. For example, and not by way of limitation, a multi-function peripheral device (MFP), which typically has the capability to perform a plurality of functions comprising a printer, scanner, copier and/or a facsimile machine or image transmitter/receiver, is a type of imaging device. Other MFP imaging devices may comprise other combinations of functions and still qualify as an IDev.

For the purposes of this specification and claims, a remote computing device (RCD) is a device capable of processing data and communicating with other devices through a communications link. An RCD is a remote device because it requires a communications link, such as a network connection, a telephone line, a serial cable or some other wired or wireless link to communicate with other devices such as an imaging device. Some exemplary RCDs are network servers, networked computers and other processing and storage devices that have communications links.

Some embodiments of the present invention may be described with reference to FIGS. 1 & 2. These embodiments comprise an imaging device (IDev) 4 that may be a multi-function peripheral device (MFP) or a single function device. The imaging device 4 further comprises a user interface (UI) panel 2, which may comprise input buttons 14 and a display device 12 or may comprise a touch panel system with or without buttons 14. User input and display may also be performed through a separate UI device 8, which may be connected to the imaging device 4 by a communication link 12, such as a USB connection, a network cable, a wireless connection or some other communications link. UI device 8 may comprise an input device, such as a keyboard or buttons as well as a display device, which may also be a touch screen panel. UI device 8 may also comprise an interface for transfer of instructions that are input to the device 8 from a remote input device. This form of UI device 8 may comprise memory sticks, USB memory cards and other storage devices that may be configured to store input for transfer to an imaging device.

These embodiments further comprise a remote computing device (RCD) 6 that is linked to the imaging device 4 via a communications link 10, such as a network connection. This network connection may be a typical wired connection or a wireless link.

Embodiments of the present invention may provide menu data from the RCD 6 to the imaging device UI panel 2 or remote panel 8 via the network connection 10. Once this menu data is fed to the imaging device 4, an UI panel 2, 8 on the imaging device 4 may be used to interact with applications that run on the remote computing device 6. User input received from UI panels 2, 8 may be returned directly to the remote computing device 6.

A Web Service is a software application identified by a Uniform Resource Identifier (URI), whose interfaces and binding are capable of being defined, described and discovered by Extensible Markup Language (XML) artifacts and that supports direct interactions with other software applications using XML based messages via Internet-based protocols.

An application on the remote computing device 6 may use one or more Web Services to control various features in the imaging device 4, such as enabling, disabling or setting device values or controlling device functions.

Embodiments of the present invention allow network applications running on remote computing devices to interact with the user of the imaging device through the imaging device I/O panel. These embodiments allow imaging device user interface (UI) control (i.e., touch panel, button/display) by applications. Some embodiments may also integrate custom display screens or menus with the native imaging device UI. Embodiments may hand off control of imaging device functions between standard operation modes performed on the imaging device in response to user input to an imaging device UI and open systems modes that utilize network resources, such as applications on RCDs, through user input at the imaging device UI.

Embodiments of the present invention comprise network-based applications that have full control over the imaging device UI to display text and graphics in any format. In these embodiments, the application can programmatically display buttons, textboxes, graphics, etc. in any layout desired.

In some embodiments, the UI layout is easy to program using a standard language, such as a markup language. These languages comprise Hypertext Markup Language (HTML), Extensible Markup Language (XML), Wireless Markup Language (WML), Extensible Hypertext Markup Language (XHTML) and other languages.

In some embodiments of the present invention a remote computing device application or server application is able to request a keyboard UI to be displayed on the imaging device display 12, 8. In some embodiments, this functionality is available on the imaging device and does not need to be recreated by remote computing device applications. In some embodiments, the remote computing device may define the keyboard prompt and default values. These embodiments may comprise a remote computing device that is able to rename imaging device UI buttons, such as the OK and Cancel buttons as well as define additional buttons.

In some embodiments, menu templates may be served to the imaging device UI by the imaging device itself 4 or from a remote computing device 6.

External Authorization Application

Some embodiments of the present invention may comprise a remote computing device application that is registered as the External Authorization server. The External Authorization application may control access to the imaging device and may have top-level control of the UI. UI control may be given to this application in the same manner that control is given to an internal auditor.

In these embodiments, when an imaging device system boots, it checks to see if an External Authorization application is registered. If so, the imaging device is placed in disabled mode and the application is contacted to take control of the UI. If the External Authorization server is not available, an error message may be displayed and the device may remain disabled. The imaging device may periodically try to contact the External Authorization server until it is available. Table 1 below describes what entity has control of the UI, in an exemplary embodiment, when the device is in a disabled state.

TABLE 1 UI Control in Disabled State Indicator Button Press UI Control Lights Device boots External Application None Document Filing External Application None Image Send External Application None Copy External Application None Job Status Device - standard Job Status screens Job Status Custom Settings Device - standard Custom Settings N/A screens OS Mode Not available when device is disabled Remote Computing Device Applications

In embodiments of the present invention, access to the custom UI panels of imaging devices may vary from application to application. Some solutions, such as Document Management integration, may wish to leverage the native Image Send screens, but display some custom UI's to gather additional information about a scan job. Other solutions, like custom printing applications, may be accessed from a separate mode than the native functions.

In order to accommodate the diversified needs of these solutions applications, embodiments may support multiple integration points for UI control. These integration points are based on a user action (“trigger”) for which applications may register. In some embodiments, applications may be registered with target devices so that the device knows that when “trigger A” occurs on the front panel to contact “remote computing device B” for instructions. In exemplary embodiments, applications may be integrated with an imaging device at any of several “trigger” points.

Remote computing devices may be registered to a specific function and contacted when that function's hardware key is pressed (e.g. Image Send) on the imaging device UI. Any UI information provided by the remote computing device may be displayed instead of the standard function screens native to the imaging device. This trigger may be used for applications that wish to replace the existing functions with completely custom UI's, such as an alternative scan solution or a specialized display, such as a “Section 508” compatible screen or other specialized-need interface that may have large buttons or other accommodations.

In some embodiments, each function on the imaging device may have a menu on the touch screen that remote computing devices, such as servers, can register. This enables solutions applications to provide custom content and still use some of the standard functionality provided by the imaging device. When a button assigned to a custom application is selected, a menu will be displayed with the solutions registered to that function. Users may select the desired solution and the remote computing device will be contacted for instructions.

In some embodiments, a stand-alone RCD mode that provides remote computing device application access can be accessed from the job queue portion of the UI that is displayed on every screen. This trigger point may be used for applications that do not fit within one of the standard device functions, such as custom printing solutions on an imaging device. When the RCD menu is selected, a menu will be displayed with the solutions applications registered to the generic RCD mode. Users will select the desired solution and the remote computing device will be contacted for instructions.

Hardware Key Interaction

In some embodiments of the present invention, when an imaging device is enabled, additional hardware keys may be used to manage the device. Hardware key assignments for an exemplary embodiment are shown in table 2.

TABLE 2 Exemplary Hardware Key Assignments Button Press Standard IDev Mode RCD Mode Mode keys (Copy, Clear current job Clear current job Doc Filing, Image settings, move to settings, move to Send) and Custom target screen target screen Settings key Job Status key Move to Job Status, Move to Job Status, maintain current maintain current settings & UI settings & UI location location Clear (C) Clears settings Sends clear event to external application Clear All (CA) Clears settings, Cancels job and cancels job, and returns to default returns to default IDev screen IDev screen (notification sent to external application) **When External Authorization is controlling the UI, only notification is sent Start Initiates scan Initiates scan function function Number keys Input for copy Not used count or fax numbers * Logs user out Logs user out (disable device (disable device and contact External and contact External Authorization for Authorization for screens) screens)

In some embodiments, in addition to the * key for logout, a timeout period may be implemented. Some embodiments also comprise an auto clear setting that can be configured for a given period of time, such as 10 to 240 seconds (or disabled). In these embodiments, when there is no activity for the time configured in auto clear, the device may automatically return to disabled mode and attempt to contact a remote computing device to retake control of the UI.

Error & Jam Notifications

Depending on a particular solution, a remote computing device application may have full or only partial control of the imaging device UI and a particular imaging job. In some embodiments, partial control may include cases where a remote computing device is monitoring clicks, but native modes are responsible for the UI interaction and controlling the job. Partial control may also include cases where the remote computing device application is integrated with a native mode (UI trigger=function custom menu). In these embodiments, the imaging device may handle all error and jam notifications with only a notification sent to the relevant remote computing device application.

For some embodiments, in cases where the remote computing device application has full control over the UI and the job, error and jam notifications may be handled differently depending on the type of error. For recoverable errors, a notification may be sent to the remote computing device application and the application may be responsible for displaying messages and resolving the error. For non-recoverable errors, the imaging device and RCD mode may interact to gracefully handle the error condition (e.g. provide user with instructions for clearing jam).

Control Handoffs

In some embodiments, at different points throughout an imaging job, several applications may need control over an imaging device including, but not limited to, an External Authorization application, a standard RCD application, an imaging device native mode and other applications. The following section describes, for an exemplary embodiment, the various steps in an exemplary job, the entities that may have control during each step, and what type of control may be allowed.

Step 1: User provides credentials to access the device at the device UI. This step may be controlled by a remote computing device, such as an External Authorization application or by Internal Accounting (native mode) in the imaging device itself. At the end of this step, the device is enabled. The External Authorization application may also specify default parameters or disable specific job parameters (e.g. default file format is PDF, but user may change; color mode is set to B/W and user may not change).

Step 2: User sets parameters for the job using one of the native imaging device modes or a standard RCD application. At the end of this step the user makes an input to initiate the job. When the input is made, an optional notification may be sent to the standard RCD application, which can then change job parameters if desired. An e-mail application is one example of an application that may request notification when the user input is made. A user may use native Image Send screens or other input to select scan options and choose e-mail recipients. A user may then select a custom application button and choose the scan-to-e-mail option from the menu. The e-mail application may then display custom screens for the user to set permissions for the file. Once a user places the original document(s) on the scanner and initiates the process, the e-mail application may capture the destination parameters set by the user and change the target destination to the e-mail application FTP server. The e-mail application may then receive the file, apply the appropriate permissions, and send to the e-mail recipients selected by the user. A remote computing device application may also want to retake control of the UI at this point, if, as in some embodiments, the application generates thumbnails of the scanned images and displays them to the user for verification.

Step 3: Once the job is initiated, the imaging device is responsible for scanning or RIPing the job and spooling it to the HDD. If the imaging device is configured to authorize jobs with an external authorization application, it may send a click report to the application and wait for instructions. The external authorization application may enable the job for sending/printing, cancel the job, or change job parameters (and then enable). As an example, a rules-based printing application may wish to change job parameters after it receives a click report. Some rules-based printing applications support rules-based printing and scanning that can limit what each user is allowed to do based on the time of day, the destination, or many other parameters. For example, only users in the marketing group may be able to scan high-quality color images. If a user from another group selects color and 600 dpi, a rules-based application may change the parameters to color and 200 dpi. At the end of this step the job should either be authorized or canceled.

Step 4: In some embodiments, this may be an optional step, where the standard RCD application in step 2 may have specified the destination as a HDD for temporary storage. This step may also be used, in some embodiments, by a Java application running on the imaging device. For example, a government office may have a custom encryption application running on the device that takes the scanned document, encrypts it, and then requests the imaging device to send it to the target destination selected by the user in step 2. In some embodiments, it may be beneficial to send a notification to the external authorization application after this step—because the imaging device does not know how long the file will be on the HDD or what the application is going to do with it—and after the send/print step.

Step 5: In the final step, the file is actually output. In typical embodiments, the file is either sent over the network or printed locally. At the end of this step, a notification that the job was successfully completed should be sent to the external authorization application and optionally, to the standard RCD application.

Device Control and Management API's

The API's may be used to allow a remote computing device application to control access to an imaging device for vend applications and to manage the device from a remote location.

Device Control and Vend API

In some embodiments of the present invention, a Device Control and Vend API allows applications to enable and disable access to the device and track click counts. The Device Control and Vend API may provide an RCD with the following controls:

Enable/disable device of function—this may allow an RCD to enable or disable access to the device as a whole or by function to enforce individual user privileges. In some exemplary embodiments, the functions listed in Table 3 may be selectively enabled or disabled by an application.

TABLE 3 Device Functions Enable/Disable Description Copy Copy function (Copy button) Image Send Scan and fax function, plus send from Doc Filing (Image Send button) Document Filing All access to Document Filing functions (Document Filing button) Print Network prints, pull print from front panel, and print from Document Filing (No button control)

Report clicks used—at the end of a successful job, the clicks used may be reported back to an RCD including:

TABLE 4 Job and Page Characteristics Fax PC- E-mail/ Broad- Scan Item Copy Print Send Fax FTP cast to HD JOB Characteristics Job Mode Yes Yes Yes Yes Yes Yes Yes Broadcast No No Yes Yes Yes Yes No Manage No. User Name Yes Yes Yes Yes Yes Yes Yes Address No No Yes Yes Yes # No Start Time Yes Yes Yes Yes Yes Yes Yes End Time Yes Yes Yes Yes Yes Yes Yes Total Page Yes Yes Yes Yes Yes Yes Yes Result Yes Yes Yes Yes Yes Yes Yes Error Cause No No Yes Yes Yes Yes No Doc Filing Yes Yes Yes Yes Yes Yes Yes Save Mode *1 *1 *1 *1 *1 *1 *1 File Name *1 Yes *1 Yes Yes *1 Yes File Size Yes Yes *1 *1 *1 *1 Yes Resolution Yes Yes Yes Yes Yes Yes Yes Special Yes Yes Yes No Yes Yes Yes Finishing Yes Yes No No No No No File Format No No No No Yes Yes No Compression No No No No Yes Yes No PAGE Characteristics Copy Yes Yes Yes Yes Yes # Yes Paper Size Yes Yes Yes Yes Yes Yes Yes Simplex/duplex Yes Yes Yes Yes Yes Yes Yes Paper Type Yes Yes Yes Yes No No Yes Page Yes Yes Yes Yes Yes Yes Yes *1 - Yes when Document Filing is used

Debit mode—in these embodiments, when an application enables the device it may specify if the current job requires authorization. If so, the job will be spooled to memory and click information (e.g., as defined in Table 4) will be sent to an RCD. An RCD will then notify the device if the job should be deleted or output/sent. At this point, the application also has the option of changing job parameters. If the application does not require authorization, the job will continue as normal and a click report will be sent at the end of the job.

Print job accounting—in these embodiments, an RCD may wish to monitor print jobs along with walk-up functions. For print job accounting, an IDev may monitor all incoming print jobs and send accounting data in the PJL header to an RCD for verification before printing the job. The RCD will evaluate the accounting data (or lack thereof) and inform the IDev to continue with or cancel the job.

Report on unidentified jobs—in these embodiments, an RCD may also wish to monitor print jobs that it cannot associate to a specific user, such as device reports and incoming fax jobs. The RCD can register to receive click counts for all unidentified jobs, so that it may bill them to a general account.

Device Management API

In some embodiments of the present invention, a Device Management API allows a network application to remotely setup and manage the imaging device. In exemplary embodiments, the Device Management API may provide an RCD with the following controls:

-   -   Device status—an RCD may request the current status of the         device. This is the same status information as reported on the         embedded web pages.     -   Device configuration—an RCD can retrieve a list of installed         options supported by the device.     -   Web Page settings—an RCD application can retrieve and set any of         the values that are configurable on the embedded web pages.     -   Key Operator Programs—an RCD application can retrieve and set         any of the values that are configurable in Key Operator         Programs, including software keys.     -   Custom Settings—an RCD application can retrieve and set any of         the values that are configurable in Custom Settings.     -   Job Status—an RCD application can retrieve the current job queue         and history information and reprioritize or delete jobs in the         queue.     -   Click counts—an RCD application can retrieve device total counts         and clicks for each function by account code.     -   Data Security settings—an RCD application may retrieve the         status information on the DSK (e.g. last erase) and initiate         data clear functions.     -   RED data—an RCD can retrieve all data typically sent in a RED         message.     -   Remote reboot—an RCD can initiate a reboot of the imaging         device.

The above groupings are provided only as an exemplary embodiment detailing which settings should be included. In some embodiments, actual API's should be grouped by functional areas since there may be overlap between Key Operator settings and web page settings.

Internal Accounting API

In some embodiments, an Internal Accounting API may allow a remote computing device application to configure internal accounting and report click counts. In some exemplary embodiments an Internal Accounting API may include:

-   -   Set Auditing Options—an RCD may set auditing options including         which modes auditing is enabled for, “account number security”,         and “cancel jobs of invalid accounts.”     -   Manage Account Codes—an RCD can add, edit, or delete account         codes     -   Account Limits—an RCD application can specify a maximum number         of clicks by function for individual account codes or for all         account codes     -   Account Reset—an RCD application can reset the click count for         an individual account or for all accounts     -   Retrieve Clicks—an RCD can retrieve the number of clicks by         function for each account code         Font and Form Management API

Some embodiments of the present invention may comprise a Font and Form Management API, which allows an RCD application to remotely download and manage fonts and forms in mass-storage. In some exemplary embodiments, a Font and Form Management API may provide a remote computing device with the following controls:

-   -   Mass storage control—an RCD application can retrieve mass         storage status information including storage capacity, space         available, and write-protect mode plus modify write-protect         status.     -   Resource list—an RCD application can retrieve a list of stored         fonts and forms including font or macro ID, font number,         font/form name, escape sequence, and file size.     -   Download resource—an RCD application can download PCL fonts, PCL         macros, and PS fonts and forms. Any special processing that is         performed when a resource is downloaded via the web pages will         also be performed when the resource is downloaded via Open         Systems.     -   Delete resource—an RCD application can delete any resource         stored in mass storage.     -   Upload resources—an RCD application can upload an individual or         all resources. On devices where effective memory management is         unavailable, a server application can use this function to         “defrag” mass storage.     -   Font/macro ID's—an RCD application can assign or modify the ID's         assigned to PCL fonts and macros.         Firmware Management API

In some embodiments of the present invention, a Firmware Management API may allow a remote computing device or network application to remotely download and manage the imaging device firmware. In some exemplary embodiments, a Firmware Management API may provide a remote computing device (e.g., a server) with the following controls:

-   -   Firmware versions—an RCD application can retrieve the current         firmware version numbers.     -   Service mode—an RCD application can place the MFP in service         mode to lockout other jobs that will interfere with firmware         upgrade. Upon receiving a service mode request, the IDev will         stop accepting incoming jobs, complete all jobs in the queue,         and then notify the server that it is in service mode.     -   Update firmware—an RCD can download an updated firmware version         to the device. If a reboot is necessary, the IDev will perform         it automatically when download is complete.     -   Download status—the IDev will send a status notification         (success/error) to an RCD after firmware download.     -   Revert to previous version—if firmware update is not successful,         the application can request the IDev to revert to the previous         firmware version.

Device Function API's

In some embodiments of the present invention, device function API's allow a remote computing device application to use existing imaging device functionality to provide new custom solutions.

Image Send API

In some embodiments, an Image Send API may provide the remote computing device application with the following controls:

-   -   Image Send Parameters—a remote computing device application can         get and set values for the following scan and fax parameters:         -   COLOR OR B/W         -   IMAGE MODE—TEXT, TEXT/PHOTO, PHOTO; EXPOSURE LEVEL         -   RESOLUTION         -   FILE FORMAT—FILE TYPE, COMPRESSION, AND PAGES PER FILE         -   ORIGINAL—ORIGINAL SIZE, SIMPLEX/DUPLEX, ROTATE, AND JOB             BUILD         -   FILENAME         -   SUBJECT         -   MESSAGE         -   SENDER         -   SCHEDULE SEND TIME         -   PAGE DIVISION (BOOK SCANNING)         -   COVER PAGE         -   TRANSMISSION MESSAGE (CONFIDENTIAL, URGENT, ETC.)         -   THIN PAPER SCANNING         -   DESTINATION         -   DOCUMENT FILING     -   Initiate Scan—the remote computing device application can         initiate the scan function (same as user pressing start button).

In some embodiments, a remote computing device can change the default values on the imaging device or the values for the current job. For the current job, the remote computing device may also specify if scan parameters may be modified by the user or not. If one remote computing device application (e.g. Access Control) specifies that a parameter cannot be changed and then a second application (e.g. Document Management) tries to set the parameter, a notification may be sent to the second application and the setting will not be changed.

Print API

In some embodiments, print jobs may be submitted by remote computing device applications using standard printing channels. In some exemplary embodiments, a Print API may provide a remote computing device with the following additional control:

-   -   PJL sniffing—an RCD application can register with the IDev to be         contacted for instructions when a specific PJL command is found         in a print job. The RCD can then instruct the IDev to replace         the command, cancel the job, or continue printing. This         interface may be used in applications like accounting and         other-brand compatibility.         Copy API

In some embodiments of the present invention, a Copy API may provide a remote computing device with the following exemplary controls:

-   -   Copy Parameters—an RCD application can get and set values for         the following copy parameters:         -   COLOR OR B/W         -   EXPOSURE—TEXT, TEXT/PHOTO, PHOTO, SUPER PHOTO; EXPOSURE             LEVEL         -   PAPER SELECT (BY TRAY)         -   COPY RATIO         -   2-SIDED COPY—1TO1, 1TO2, 2TO2, 2TO1; BINDING EDGE         -   OUTPUT—OUTPUT TRAY, SORT, STAPLE, GROUP, OFFSET         -   ORIGINAL SIZE         -   SPECIAL FUNCTIONS—MARGIN SHIFT, ERASE, PAMPHLET, ETC.         -   DOCUMENT FILING     -   Initiate Copy—an RCD application can initiate the copy function         (same as user pressing start button).

In some embodiments, a remote computing device can change the default values on the imaging device or the values for the current job. For the current job, the remote computing device may also specify if copy parameters may be modified by the user or not.

Document Filing API

In some embodiments of the present invention, a Document Filing API may provide a remote computing device with the following exemplary controls:

-   -   Backup/restore—the remote computing device application can         import and export a batch file with all Document Filing data. In         some embodiments, this package will be in a proprietary format         since it contains documents that are password-protected and         should not be accessed individually—this is typically for         restore in case of failure or cloning to other devices.     -   File/folder list—the remote computing device application can         retrieve, modify, and create new files and, folders to be stored         on the IDev (also covered in device management).     -   Download file—the remote computing device can download a new         file to the Document Filing systems and specify folder,         filename, username, and password.     -   User list—the remote computing device application can retrieve,         modify, and create new users to be stored on the IDev (also         covered in device management).     -   HDD Status—the remote computing device application can retrieve         the current HDD status including the % allocated to the main         folder, quick folder, and custom folders and the % remaining.     -   Doc Filing Parameters—the remote computing device application         can get and set values for storing a file to Doc Filing         including:         -   EXPOSURE         -   RESOLUTION         -   ORIGINAL—SIZE, SIMPLEX/DUPLEX         -   FILE INFORMATION—USERNAME, FILENAME, FOLDER, CONFIDENTIAL,             PASSWORD         -   SPECIAL MODES—ERASE, DUAL PAGE COPY, 2IN1, JOB BUILD, CARD             SHOT     -   Initiate Print—the remote computing device application can         select a stored file and initiate a print including the         following parameters:         -   PAPER SIZE/SOURCE         -   OUTPUT—SORT/GROUP, OUTPUT TRAY, STAPLE, PUNCH, OFFSET         -   SIMPLEX/DUPLEX (TABLET/BOOKLET)         -   TANDEM PRINT         -   NUMBER OF COPIES         -   DELETE OR STORE AFTER PRINTING     -   Initiate Send—the remote computing device application can select         a stored file and initiate a send including the following         parameters:         -   RESOLUTION         -   FILE FORMAT         -   DESTINATION         -   TIMER         -   SENDER         -   FILENAME         -   SUBJECT         -   MESSAGE

Security

Allowing external applications to control an imaging device opens up the imaging device to new security vulnerabilities. In embodiments of the present invention that provide some security measures, the following exemplary items are security concerns that may be addressed by the remote computing device interface.

Access to remote computing device interfaces may be limited to valid applications. Embodiments provide extensive access and control of the imaging device, which poses a significant security risk. The interface of these embodiments may be protected from access by attackers, while maintaining ease of setup and use for valid solutions.

Confidential data (user credentials and job data) may be protected during network transfer. User credentials and job data may be secured during network transfer to ensure that it cannot be stolen, an intruder cannot monitor device activity, and a man-in-the-middle attack cannot change messages. Imaging devices may support Secure Sockets Layer (SSL) and other connections to ensure data is safe while being communicated between the imaging device and remote computing device applications.

Administrators may have the ability to lock-down imaging device access. For users with strict security policies, administrators may have the ability to disable access by remote computing devices or limit access to specific applications. Administrators may have an option to register the limited applications that they wish to access the imaging device interfaces.

Remote computing device applications may ensure the imaging device is not being “spoofed.” The remote computing device may be able to authenticate an imaging device that it is contract with it to ensure an intruder cannot imitate the imaging device to collect network configuration and password information, monitor file/folder structures of a document management system, or spoof security settings and DSK status of the imaging device.

A remote computing device may ensure that the server is not being “spoofed.” The imaging device must be able to authenticate all remote computing devices that it is in contact with to ensure that an intruder is not spoofing the remote computing device's IP address. By pretending to be the remote computing device, an intruder could steal user credentials, redirect scanned documents, change device settings or firmware, or bring down the access control system (either to provide access to unauthorized users or initiate a denial of service attack for valid users).

Access control/vend applications may not be compromised when a remote computing device is unavailable. When the remote computing device is unavailable, it may not be acceptable to provide open access to the device. If the remote computing device is unavailable at startup or becomes unavailable at anytime (e.g. someone disconnects network cable), the imaging device may immediately be disabled and an error message displayed.

An administrator may be able to adjust a security level based on company and application requirements. Security requirements can have a large impact on the time it takes to develop a remote computing device application and the resources required to implement the solution. Users using some embodiments may range from a small business with one imaging device, no IT staff, and a simple scan or print application to a large government office using access control and audit trails to track all device activity. The security measures used to protect imaging device interfaces may be adjustable by the administrator to match the target environment.

The imaging device and remote computing device applications may be able to hand-off user credentials. Users may be prompted to login at multiple points throughout a job. For example, an access control application or accounting application may control total device access, the imaging device may have user authentication enabled for Image Send, and a document management application may require user login before showing a folder list. In many environments, all of these applications will use a common user database. In some embodiments, it is, therefore, desirable for the applications to pass user credentials to each other, so that each one does not have to repeat the authentication process.

Some embodiments of the present invention may be described with reference to FIG. 3. These embodiments comprise an imaging device only, which is configured to interact with a remote computing device, such as a server through a communications link. The imaging device 30 comprises a user interface 32, which comprises a user input device 34, such as a keypad, one or more buttons, knobs or switches or a touch-screen panel and a display 36, which may comprise user input device 34 in the form of a touch-screen panel.

Imaging device 30 will typically be capable of performing one or more imaging functions including, but not limited to, scanning, printing, copying, facsimile transmission (sending and receiving) and others.

These embodiments further comprise a communications link 38, which may be a wired connection (as shown in FIG. 3) comprising a network cable, a Universal Serial Bus (USB) cable, a serial cable, a parallel cable, a power line communication connection such as a HomePlug connection or other wired connections. Alternatively, the communications link 38 may comprise a wireless connection, such as an IEEE 802.11(b) compliant connection, a Bluetooth connection, an Infrared Data Association (IrDA) connection or some other wireless connection.

The operation of some imaging device embodiments may be explained with reference to FIG. 4. In these embodiments, menu data is received 40 from a remote computing device (not shown in FIG. 3), which is connected to the imaging device 30 via the communication link 38 through a wired or wireless connection. This menu data is then displayed 42 on the imaging device user interface display 36. This display of remote menu data is intended to prompt a user to make an input on the user interface input device 34.

Imaging devices of these embodiments are further configured to accept input from a user in response to a display of remote menu data and communicate 44 that user input to a remote computing device. In some embodiments, this user input data will be processed by a remote computing device. This may comprise running an application on the remote computing device. This processing may also comprise accessing and communicating data that is stored on the remote computing device.

The imaging devices of these embodiments are further configured to receive 46 data resulting from processing the user input data. This may comprise data generated by an application running on the remote computing device in response to the user input. The imaging device may also receive data that was stored on a remote computing device, such as a file server, in response to processing the user input.

Once the imaging device 30 has received 46 the processed data, the imaging device 30 may perform 48 a native function in response to the data or using the data. For example, and not be way of limitation, the imaging device 30 may print a document that was stored on the remote computing device and modified on the remote computing device according to the user input. As another non-limiting example, the imaging device 30 may active or enable functions (i.e., scanning, copying, printing, fax transmission) on the imaging device in response to the receipt 46 of processed data.

Some, more specific, imaging device embodiments may be explained with reference to FIG. 5. In these embodiments, the imaging device 30 is configured to receive 50 menu data formatted in a markup language from a remote computing device. The communication link by which the menu data is communicated may be established and maintained using a Hypertext Transfer Protocol (HTTP). The markup language may comprise terms from Hypertext Markup Language (HTML), Extensible Markup Language (XML), Wireless Markup Language (WML), Extensible Hypertext Markup Language (XHTML) and/or other languages.

Once the menu data is received 50, it may be displayed 52 on the imaging device user interface display 36. As in previously described embodiments, the menu data is typically intended to prompt user input on imaging device user interface 32. Display 52 of the remotely-stored menu data may be accomplished with a browser application that is native to the imaging device 30.

In these embodiments, the imaging device 30 is further configured to route 54 user input received though its user interface 32 to a remote computing device. The remote computing device that receives the user input may then run an application or otherwise process the user input and return the results of the processing to the imaging device 30. Accordingly, the imaging device 30 is further configured to receive 56 processed data from a remote computing device. In some embodiments, the imaging device 30 may perform one or more functions in response to the receipt 56 of processed data.

Some embodiments of the present invention may be explained with reference to FIG. 6. These embodiments comprise a remote computing device (RCD) 60, which has a communications link 64. Communications link 64 may be a wired connection (as shown in FIG. 6) comprising a network cable, a Universal Serial Bus (USB) cable, a serial cable, a parallel cable, a powerline communication connection such as a HomePlug connection or other wired connections. Alternatively, the communications link 64 may comprise a wireless connection, such as an IEEE 802.11(b) compliant connection, a Bluetooth connection, an Infrared connection, such as those defined in the Infrared Data Association (IrDA) standard or some other wireless connection. In some embodiments, RCD 60 may further comprise a data storage device 62, which is typically a hard drive, but may also be an optical drive device, such as an array of compact disk drives, flash memory or some other storage device.

Embodiments of RCD 60 may be further described with reference to FIG. 7. In these embodiments, RCD 60 comprises a processor 72 for processing data and running programs such as operating systems and applications. RCD 60 may further comprise memory 74, which may be in the form of Random Access Memory (RAM) and Read Only Memory (ROM). Generally, any applications processed by processor 72 will be loaded into memory 74. RCD 60 may further comprise a network interface 78, which allows RCD 60 to communicate with other devices, such as an imaging device 30. In some embodiments, RCD 60 may also comprise a user interface 80, but this is not required in many embodiments. Storage 62 may be used to store applications and data that may be accessed by an imaging device 30 of embodiments of the present invention. Processor 72, memory 74, storage 62, network interface 78 and, optionally, user interface 80 are typically linked by a system bus 76 to enable data transfer between each component. Communications link 64 may couple the RCD 60 to other devices via network interface 78.

In some embodiments, described with reference to FIG. 8, an RCD 60 may comprise menu data stored on storage device 62 or in memory 74. This menu data may be configured for display on an imaging device user interface 32. Menu data may be stored in many formats and configurations. In some embodiments menu data may take the form of terms expressed with a markup language. The markup language may comprise terms from Hypertext Markup Language (HTML), Extensible Markup Language (XML), Wireless Markup Language (WML), Extensible Hypertext Markup Language (XHTML) and/or other languages. In these embodiments, menu data may be sent 82 through a communications link 64 to an imaging device 30. Accordingly, menu data configured for display on an imaging device is stored on RCD 60.

An RCD 60, of some embodiments, will be further configured to receive 84 user input obtained through the user interface 32 of an imaging device 30 and transferred to the RCD 60 over communications links 38 & 64. Once this input data is received at an RCD 60, the input data may be processed 86. This processing 86 may comprise conversion of the data to a new format, execution of commands contained within the data or some other process. Once the input data has been processed 86, the processed output may be sent 88 back to the imaging device 30 where the processed output may be used in an imaging device process or function.

In some embodiments, as described with reference to FIG. 9, an RCD 60 may send 90 menu data configured for an imaging device display 36 using a markup language. The markup language menu data is then received at the imaging device 30 and displayed to a user. Typically, this will prompt the user to enter an input on the imaging device user interface 32. This user input will then be sent by the imaging device 30 to the RCD 60. The RCD 60 will then receive 92 the input data prompted by the display of the menu data on the imaging device 30. Once received, the input data may be processed 94 on the RCD 60. Processing may comprise the selection, recordation and/or modification of a form, document or other data stored on RCD 60, the authorization of a user identified by the user input, the translation of a document input by the user, generation of a map or other directions related to user input or some other process or function.

Some embodiments of the present invention may be described with reference to FIGS. 10 & 11. These embodiments comprise at least one RCD 60 and a plurality of imaging devices 30 a-30 d. In these embodiments, at least one of the imaging devices 30 a-30 d comprises a user interface 32 with a display 36 and user input panel 34 that is integral with the display (i.e., touch-screen) or a separate input unit. RCD 60 is connected to imaging devices 30 a-30 d by a communications link and network 100 to enable data transmission between RCD 60 and imaging devices 30 a-30 d.

In these embodiments, menu data is stored on RCD 60 and sent 110 to at least one of the imaging devices 30 a-30 d where the menu data is displayed on a user interface. Any of Imaging devices 30 a-30 d that receive the menu data are configured to accept 112 and transmit 114 user input to an RCD 60. Once the user input data is received at the RCD, the data may be processed 116 as discussed in previously described embodiments. The result of processing 116 may then be sent 118 back to any combination of the imaging devices 30 a-30 d.

In these embodiments, a single RCD 60 may be used to provide processing power, resources and functionality to a plurality of imaging devices 30 a-30 d without reproducing these resources in each imaging device. In some embodiments, data generated by input on one imaging device 30 a may be directed to another imaging device 30 d for processed data output or final processing.

Some embodiments of the present invention may be described with reference to FIG. 12. In these embodiments, an imaging device (IDev) 120 comprises a user interface 124, which is capable of receiving user input and displaying data to a user. The user interface 124 will typically comprise a display, often in the form of a touch panel. The display may be used to display data to a user. This data may comprise menu data to prompt for a user selection or data entry, such as a user ID and password, form selection or some other input. The imaging device 120 has a communication link 122, which may comprise a typical computer network connection, a serial cable or some other wired or wireless communication link as described in other embodiments. The communication link 122 may connect the imaging device 120 to a remote computing device (RCD) 126 a, 126 b, such as a server. The RCD 126 a, 126 b may be used to store documents, such as forms, and other data and make that data accessible from the imaging device 120. The RCD 126 a, 126 b may also execute applications that interact with or receive input from the imaging device 120 and its user interface 124. In some embodiments, a database 125 may be linked to the imaging device 120 and/or an RCD 126 a, 126 b. In some embodiments, an RCD 126 b or database 125 may be connected to an IDev 120 over a wide area network such as the internet 128.

Some embodiments of the present invention may be described with reference to FIG. 13. In these embodiments, one or more imaging devices (IDev) 130 a-130 c, comprising user interfaces 134 a-134 c, which are capable of receiving user input and displaying data to a user. The user interfaces 134 a-134 c will typically comprise displays, often in the form of a touch panel. The displays may be used to display data 122 to a user. The imaging devices 130 a-130 c have a communication link 132, which may comprise a typical computer network connection, a serial cable or some other wired or wireless communication link as described in other embodiments. The communication link 132 may connect the imaging devices 130 a-130 c to one or mores remote computing devices (RCD) 136 a, 136 b, such as a server. The RCDs 136 a, 136 b may be used to store documents, such as forms, and other data and make that data accessible from the imaging devices 130 a-130 c. The RCDs 136 a, 136 b may also execute applications that interact with or receive input from the imaging devices 130 a-130 c and their user interfaces 134 a-134 c. In some embodiments, a database 135 may be linked to the imaging devices 130 a-130 c and/or the RCDs 136 a, 136 b. In some embodiments, an RCD 136 b or database 135 may be connected to an IDev 130 a-130 c over a wide area network such as the internet 138.

Concurrent Account Use Accounting Embodiments

Some embodiments of the present invention comprise methods and systems that provide for concurrent use of a peripheral device user account. In a typical peripheral device system, concurrent use of the same user account by more than one user is not allowed. For example, in a typical peripheral device accounting system, two users sharing a single account cannot access devices that will charge fees to the same account during the same period of time. In current systems the first user to login is allowed to proceed with his job while the second is denied permission.

In known accounting systems for peripheral device access, only a single user may login to a user account at a time. Subsequent users must wait until the first user has completed a job to commence any subsequent jobs. Typically, an imaging system will perform a requested job and then, upon completion of that job, deduct the job amount from the user account. Because the job charges are not known in advance, multiple users cannot use the same account as one user may deplete the account finds while multiple jobs are being executed. Consequently, known systems lack the ability to allow multiple users to login concurrently to the same account.

Embodiments of the present invention comprise methods and systems that have the capability to calculate job charges before execution of the job and to deduct the charges from an account before execution of the job. Using these systems and methods allows multiple users to use an account without the risk of exceeding account limits. Once account limits are reached, no further jobs will be authorized. A system with the ability to allow multiple users sharing the same account to concurrently login to multiple imaging devices and run multiple jobs simultaneously while charging the jobs to the same account can allow a group to operate more efficiently and more profitably.

Embodiments of the present invention provide for multiple concurrent account users by calculating the charges associated with a proposed imaging job and deducting those charges from the account or otherwise adjusting the account to account for the job charges. This is done before execution of the job so that account limits will not be exceeded by other jobs that occur within the same period of time. In some embodiments, these job charges may be estimated. These estimates may be performed conservatively and may result in an overcharge to the account that can be rectified after a more accurate job charge is calculated. Some embodiments may comprise systems and methods that perform a rough or conservative jog charge estimate that is deducted or otherwise settled against the account. In these embodiments, a more accurate job charge may be calculated during or after execution of the job and the more accurate charge may result in a further adjustment to the account. While the account may be temporarily overcharged, account limits are not exceeded despite concurrent account use.

Some embodiments of the present invention may comprise limits on the number of concurrent account users. These limits may be related to the ability of the system to accurately estimate the appropriate charges for an imaging job. When job charges cannot be accurately estimated, the number of concurrent users may be limited to a small number. When job charges can be estimated with extreme accuracy, a high number of concurrent users may be allowed. The accuracy of job charge estimates may be related to the specific type of imaging job. Some jobs, such as image scanning to a file, may be accurately predicted without details of the actual document to be scanned while some jobs, such as color copying, may require pixel counts and detailed job parameters to accurately estimate job charges. Because of these varying job charge estimation factors, the accuracy of the total amount charged to an account may vary depending on the types of jobs in progress at any period of time. To account for this estimated charge inaccuracy, the number of concurrent account users may be limited to a specific number or may be limited to a variable number that is dependent on the types of jobs currently in progress in the system. Accordingly, the number of concurrent account users may be limited to a fixed number or a variable number. This limit on the number of concurrent account users may be may be affected by many factors and may or may not be related to the accuracy of estimated job charges.

Some embodiments of the present invention comprise imaging job configuration capabilities that define elements of an imaging job. A typical multi-function peripheral (MFP) imaging device has the capability to scan, print, fax and copy documents. Some MFPs may also have e-mail functions as well. Many MFPs allow a job to be configured in great detail. Scan or copy jobs may allow a user to zoom or magnify an image, crop the image, sharpen the image, modify color characteristics and select many other features. Print and copy jobs may allow a user to select color options, darkness levels, N-Up formatting, paper size and many other features. Imaging jobs may be configured to comprise many functions and elements.

Generally, an imaging job can be broken down into elemental functions and processes that are accomplished by different parts of the imaging device. For example, a simple copy job can be broken down into a scan process and a print process. More complex copy jobs may comprise zooming, cropping, rotating, sharpening, page formatting and other elemental functions. These elemental functions and their attributes may be referred to as detailed job parameters. Detailed job parameters comprise media type, media size, media quantity, quantity of impressions per page, pixel count data, image resolution, finishing operations, stapling requirements, punching requirements, collating requirements, color attributes, color depth, color quantity, ink consumption, toner consumption, contrast media consumption, monochrome attributes, grey-scale attributes, double-sided characteristics, single-sided characteristics, N-Up formatting, paper tray selection, scan destination, print destination, power consumption, job type (i.e., print, copy, scan, facsimile, and document management) and many other parameters.

In some embodiments of the present invention, job costs, fees and/or charges may be calculated in relation to job configuration data and, in some embodiments, in relation to detailed job parameters as described above.

Some embodiments of the present invention may comprise an imaging device (IDev) in communication with one or more additional IDevs or one or more remote computing devices (RCDs).

Some embodiments of the present invention may be described with reference to FIGS. 10, 12 & 14. These embodiments may comprise an IDev 120, 30 a-30 d that is capable of receiving 140 account ID data from a user. This account ID data may be received directly from a user through an UI on the IDev 120, 30 a-30 d. Account ID data may also be transmitted from a remote device that has received user input directly. Account ID data may also be received as a set of commands from another device in an automated system or from other sources. Once account ID data is accepted the IDev 120, 30 a-30 d may receive job configuration data from a user. This job configuration data may be received directly from a user through an UI on the IDev 120, 30 a-30 d. Job configuration data may also be transmitted from a remote device that has received user input directly. Job configuration data may also be received as a set of commands from another device in an automated system or from other sources. Once this job configuration data is received, it may be sent 142 to an RCD 60, 126 a-b for processing. An accounting application running on the RCD 60, 126 a-b may then calculate 144 job costs and fees from the job configuration data and/or detailed job parameters. Once costs, fees or charges are calculated for the job, they may then be compared 145 by the accounting application with accounting restrictions and an account verification process may be employed whereby the fees for the current job are compared to a user's account to verify 146 that there is sufficient account capacity. Account capacity may represent an amount of funds available in a debit account, an amount of credit available on a credit account or some other metric in an accounting system. Based on this account verification process 146, a job may be approved 148 or denied 147.

When this determination has been made and the job configuration receives accounting approval the job amount may be deducted 148 from a user account prior to execution of the job. In these embodiments, the charges for the current job may be deducted by reducing an amount of funds available in a debit account, decreasing an amount of credit available on a credit account or adjusting some other metric in an accounting system. The IDev 120, 30 a-30 d may then execute 149 the job as configured. If the job configuration does not receive accounting approval, the job request may be denied 147 and the job will not be executed.

In some exemplary embodiments, related to those depicted in FIG. 14, a user may login 140 to an imaging device using an account ID. A user may also read prompts in the form of text and graphics displayed on an imaging device UI display. In response to these prompts, the user may input job configuration data using the IDev UI. A user may also input data directly without a prompting procedure. For example, a user may select a high-resolution, color, copy function that enlarges the image by 100% and applies a filter to sharpen the image and finally prints the image on photographic media paper. This input is accepted 141 by the IDev and sent to an accounting application for processing. The IDev may then calculate 144 job costs using this job configuration data. The costs, fees or charges associated with the job may be compared with accounting restrictions. In a debit account scenario, the user's account may be checked to verify 146 that funds have been deposited to cover the cost of the imaging job. If the account has sufficient funds, a job may be approved 148 by the accounting system and the job amount deducted from the user account prior to the execution of the job. The imaging device may then proceed with execution 149 of the job as configured. If the account does not have sufficient funds, the job will be denied 147 and will not be allowed to execute on the imaging device.

Some embodiments of the present invention may be described with reference to FIGS. 10, 12 & 15. These embodiments may comprise an IDev 120, 30 a-30 d that is capable of receiving 150 account ID data from a user as described above. Once account ID data is received, the IDev 120, 30 a-30 d may 151 prompt for and/or receive job configuration data from a user. This job configuration data may be received directly from a user through an UI on the IDev 120, 30 a-30 d. Job configuration data may also be transmitted from a remote device that has received user input directly. Job configuration data may also be received as a set of commands from another device in an automated system or from other sources. Once this job configuration data is received, it may be sent 152 to an RCD 60, 126 a-b for processing. As in some other embodiments, an accounting application running on the RCD 60, 126 a-b may then calculate 154 job costs, fees or charges based on the job configuration data. In some embodiments, costs, fees or charges may be calculated based on detailed job parameters. Once costs and fees are calculated for the job, they may then be compared 155, by the accounting application, with accounting restrictions and an account verification process may be employed as described above. When this determination has been made, and the job configuration receives accounting approval, the job charges may be applied 158 to user account and the IDev 120, 30 a-30 d may execute the job 159 as configured. In some embodiments, if the job configuration does not receive accounting approval, the job may be reconfigured 157 to a configuration that meets accounting restrictions and the reconfigured job may be sent to the IDev 120, 30 a-30 d for execution. If the account restrictions will not allow the job 157, the IDev may modify the job, by limiting a job parameter or by some other means, until the job costs or fees fall within accounting restrictions. For example, and not by way of limitation, a job that has been configured for 50 copies may be limited to 30 copies when a user's account only has sufficient funds to cover 30 copies. As another non-limiting example, a job may be changed from color copies on photo paper to color copies on bond paper when this change will bring the job into compliance with accounting restrictions.

Some embodiments of the present invention may be described with reference to FIGS. 10, 12 & 16. These embodiments comprise an IDev 120, 30 a-30 d that is capable of receiving 160 account ID data from a user as described above. Once account ID data is received the IDev 120, 30 a-30 d may 161 prompt for and/or receive job configuration data from a user. This job configuration data may be received directly from a user through an UI on the IDev 120, 30 a-30 d. Job configuration data may also be transmitted from a remote device that has received user input directly. Job configuration data may also be received as a set of commands from another device in an automated system or from other sources. Once this job configuration data is received, it may be sent 162 to an RCD 60, 126 a-b for processing. As in some other embodiments, an accounting application running on the RCD 60, 126 a-b may then calculate 164 job costs, fees or charges based on the job configuration data. Once costs, fees or charges are calculated for the job, they may then be compared 166 by the accounting application with accounting restrictions and an account verification process may be employed as described above. When this determination has been made and the job configuration receives accounting approval, the job charges may be applied 168 to the user account and the IDev 120, 30 a-30 d may execute the job 169 as configured. In these embodiments, if account restrictions are not met 167, a user may be prompted to modify the job configuration. This may be accomplished by input on an imaging device user interface. In some embodiments, the IDev may prompt the user with data indicating which configuration characteristics may be changed to make the job comply with accounting restrictions.

Some embodiments of the present invention may be described with reference to FIGS. 10, 12 & 17. These embodiments comprise an IDev 120, 30 a-30 d that is capable of receiving 170 account ID data. This account ID data may be received directly from a user through an UI on the IDev 120, 30 a-30 d. Account ID data may also be transmitted from a remote device that has received user input directly. Account ID data may also be received as a set of commands from another device in an automated system or from other sources. Once this account ID data is received 170, it may be sent 171 to an RCD 60, 126 a-b for processing. The RCD 60, 126 a-b may process the data and determine whether the job complies with concurrent user account restrictions. For example, and not by way of limitation, an account with a concurrent user maximum set at three will not allow a fourth concurrent user to login to the account. As another non-limiting example, an account with the concurrent user feature disabled will not allow more than one user to login. If the concurrent user limit is exceeded, a user will be denied 173 access to system functions. When this determination has been made and the concurrent account user receives accounting approval the IDev 120, 30 a-30 d may 174 prompt for job configuration data from a user as described above. Once this job configuration data is received, it may be sent 175 to an RCD 60, 126 a-b for processing. As in some other embodiments, an application running on the RCD 60, 126 a-b may then calculate 176 job costs, fees and charges from the job configuration data. Once costs, fees and charges are calculated for the job, the application may process the data and determine whether the job complies with accounting restrictions as described above. When this determination has been made and the job configuration receives accounting approval, the job charges may be applied 178 b to the user account as described above and the IDev 120, 30 a-30 d may execute the job 179 as configured. If the job does not receive accounting approval, the job request may be denied 178 a and the job will not be executed.

Some embodiments of the present invention may be described with reference to FIGS. 10, 12 & 18. These embodiments comprise an IDev 120, 30 a-30 d that is capable of receiving 180 account ID data from a user as described above. Once this account ID data is received 180, it may be sent 181 to an RCD 60, 126 a-b for processing. The RCD 60, 126 a-b may process 182 the data and determine whether the job complies with concurrent user account restrictions as described above. When this determination has been made and the concurrent account user receives accounting approval the IDev 120, 30 a-30 d may prompt 184 for job configuration data from user. This job configuration data may be received as described above. Once this job configuration data is received, it may be sent 185 to an RCD 60, 126 a-b for processing. As in some other embodiments, an application running on the RCD 60, 126 a-b may then calculate 186 job costs, fees and charges from the job configuration data. Once costs, fees and charges are calculated for the job, the application may process the data and determine whether the job complies with accounting restrictions 187. When this determination has been made and the job configuration receives accounting approval, the job charges may be applied 188 b to the user account and the IDev 120, 30 a-30 d may execute the job 189 as configured. In some embodiments, if the job configuration does not receive accounting approval, the job may be reconfigured 188 a to a configuration that meets accounting restrictions and the reconfigured job may be sent to the IDev 120, 30 a-30 d for execution. If the account restrictions will not allow the job 188 a, the IDev may modify the job, by limiting a job parameter or by some other means, until the job costs, fees or charges fall within accounting restrictions. For example, and not by way of limitation, a job that has been configured for 50 copies may be limited to 30 copies when a user's account only has sufficient finds to cover 30 copies. As another non-limiting example, a job may be changed from color copies on photo paper to color copies on bond paper when this change will bring the job into compliance with accounting restrictions.

Some embodiments of the present invention may be described with reference to FIGS. 10, 12 & 19. These embodiments comprise an IDev 120, 30 a-30 d that is capable of receiving 190 account ID data from a user as described above. Once this account ID data is received 190, it may be sent 191 to an RCD 60, 126 a-b for processing. The RCD 60, 126 a-b may process 192 the data and determine whether the job complies with concurrent user account 30 restrictions as described above. When this determination has been made and the concurrent account user receives accounting approval the IDev 120, 30 a-30 d may prompt 194 for job configuration data from user. This job configuration data may be received as described above. Once this job configuration data is received, it may be sent 195 to an RCD 60, 126 a-b for processing. As in some other embodiments, an application running on the RCD 60, 126 a-b may then calculate 196 job costs, fees and charges from the job configuration data. Once costs, fees and charges are calculated for the job, the application may process the data and determine whether the job complies with accounting restrictions 197. When this determination has been made and the job configuration receives accounting approval, the job charges may be applied 198 b to the user account and the IDev 120, 30 a-30 d may execute the job 199 as configured. In these embodiments, if account restrictions are not met, a user may be prompted 198 a to modify the job configuration. This may be accomplished by input on an imaging device user interface. In some embodiments, the IDev may prompt the user with data indicating which configuration characteristics may be changed to make the job comply with accounting restrictions.

Some embodiments of the present invention, illustrated in FIG. 20, comprise an IDev 120, 30 a-30 d that is capable of receiving 200 account ID data from a user as described above. Once account ID data is accepted the IDev 120, 30 a-30 d may receive 201 job configuration data. This job configuration data may be received as described above in relation to other embodiments. Once this job configuration data is received, it may be sent 202 to an RCD 60, 126 a-b for processing. As in some other embodiments, an accounting application running on the RCD 60, 126 a-b may then calculate 203 job costs, fees and charges from the job configuration data. Once costs, fees and charges are calculated for the job, they may then be compared 204 by the accounting application with accounting restrictions. When this determination has been made and the job configuration receives accounting approval, the job charges may be applied 205 b to the user account and the IDev 120, 30 a-30 d may execute the job 206 as configured. If the job configuration does not receive accounting approval, the job request may be denied 205 a and the job will not be executed.

During processing of the job many things can occur that may give the system additional data to better calculate job costs, fees and charges. Additionally, errors may occur that may change the outcome of a job and its associated costs, fees and charges. For example, the cost of toner for a particular imaging job may be estimated the initial calculation of job costs, fees and charges. Once the job has completed, the system may have the capability to measure the exact amounts of toners used to complete the job. When there is a significant difference between the originally calculated costs, fees or charges and the post-job-execution calculations for job costs, fees or charges, adjustments may be made to the account to reflect the more accurate costs, fees or charges.

Errors may also occur during processing of an imaging job. These errors may affect the final job product such that it differs from what the user originally configured. For example, a paper jam may occur when a job is partially complete. Without manual intervention, the job will terminate without completion. When this occurs, the job costs, fees and charges may be recalculated to reflect the costs, fees and charges of the portion of the job that is complete.

Consequently, some embodiments of the present invention comprise systems and methods for calculating the costs, fees or charges of a specific job once the job has been completed and adjusting the costs, fees and charges applied to a user account after completion of a job. The results of these calculations may be reflected in a job result report. The term “job results” comprises the results of these calculations as well as other data related to an imaging job and its execution.

In these embodiments, the IDev, 120, 30 a-30 d may send job results 207 to an RCD 60, 126 a-b for processing. In these embodiments, an accounting application running on the RCD 60, 126 a-b may determine if the job was completed successfully and within accounting parameters. If the job was not completed successfully or if an accounting parameter exceeded its limits, the application may adjust the costs, fees or charges applied to the user's account. For example, and not by way of limitation, if a job that has been configured for 50 copies and the system only completes 25 copies before the device depletes its paper supply, the application may refund the amount for 25 copies back to user's account. As another non-limiting example, if a job has been configured for 20 copies and the system only completes 10 before the toner is depleted, the application may refund the costs, fees or charges associated with the 10 pages that were not completed. As an additional non-limiting example, a job may be configured for a fixed number of pages of color copies. Before job execution, the job costs, fees or charges are calculated using estimated amounts of toners. These costs, fees or charges are then applied to the user's account prior to job execution. During or after job execution, the actual amounts of toners may be measured accurately and the actual costs, fees or charges may be very accurately calculated. In this example, the costs, fees or charges based on the actual job consumption are significantly lower than the estimated costs, fees or charges applied to the account before execution. In this situation, the difference between the initial and subsequent charges is refunded to the user's account.

In these embodiments, when the initial costs, fees or charges differ significantly from the more accurate costs, fees or charges calculated during or after job completion, an adjustment may be applied 208 to the user's account to reflect this difference. This adjustment may take the form of a refund, an additional charge or some other adjustment. When no significant difference is calculated, the process may terminate 209 without further adjustment.

Further embodiments of the present invention may be described with reference to FIGS. 10, 12 & 21. These embodiments comprise an IDev 120, 30 a-30 d that is capable of receiving 210 account ID data from a user. Once account ID data is accepted, the IDev 120, 30 a-30 d may prompt 211 for job configuration data from a user. This job configuration data may be received as described above. Once this job configuration data is received, it may be sent 212 to an RCD 60, 126 a-b for processing. As in some other embodiments, an accounting application running on the RCD 60, 126 a-b may then calculate 213 job costs, fees or charges from the job configuration data. Once costs, fees or charges are calculated for the job, they may then be compared 214, by the accounting application, with accounting restrictions as described above. When this determination has been made and the job configuration receives accounting approval, the job charges may be applied 215 b to the user account and the IDev 120, 30 a-30 d may execute the job 216 as configured. In some embodiments, if the job configuration does not receive accounting approval, the job may be automatically reconfigured 215 a to a configuration that meets accounting restrictions, as described above, and sent to the IDev 120, 30 a-30 d for execution.

In some of these embodiments, the IDev, 120, 30 a-30 d may send 217 job results to an RCD 60, 126 a-b for processing. In these embodiments, an accounting application running on the RCD 60, 126 a-b may determine, through the use of the job results, if the job was completed successfully and within accounting parameters. If the job was not completed successfully and/or was not completed within accounting parameters, the application may then adjust the user's account 218 to account for the difference in costs, fees or charges. If the job is found to have been completed successfully and within accounting parameters, the process may continue without further adjustment 219.

Further embodiments of the present invention may be described with reference to FIGS. 10, 12 & 22. These embodiments comprise an IDev 120, 30 a-30 d that is capable of receiving 220 account ID data from a user. Once account ID data is accepted, the IDev 120, 30 a-30 d may prompt 221 for job configuration data from a user. This job configuration data may be received as described above. Once this job configuration data is received, it may be sent 222 to an RCD 60, 126 a-b for processing. As in some other embodiments, an accounting application running on the RCD 60, 126 a-b may then calculate 223 job costs, fees or charges from the job configuration data. Once costs, fees or charges are calculated for the job, they may then be compared 224, by the accounting application, with accounting restrictions as described above. When this determination has been made and the job configuration receives accounting approval, the job charges may be applied 225 b to the user account and the IDev 120, 30 a-30 d may execute the job 226 as configured. In some embodiments, if the job configuration does not receive accounting approval, a user may be prompted 225 a to modify the job configuration. This may be accomplished by input on an imaging device user interface. In some embodiments, the IDev may prompt the user with data indicating which configuration characteristics may be changed to make the job comply with accounting restrictions.

In some of these embodiments, the IDev, 120, 30 a-30 d may send 227 job results to an RCD 60, 126 a-b for processing. In these embodiments, an accounting application running on the RCD 60, 126 a-b may determine, through the use of the job results, if the job was completed successfully and within accounting parameters. If the job was not completed successfully and/or was not completed within accounting parameters, the application may then adjust the user's account 228 any over-deducted amount to the user's account as described above. If the job is found to have been completed successfully and within accounting parameters, the process may continue without further adjustment 229.

Some embodiments of the present invention may be described with reference to FIGS. 10, 12, 23A & 23B. These embodiments comprise an IDev 120, 30 a-30 d that is capable of receiving 230 account ID data from a user as described above in relation to other embodiments. Once this account ID data is received 230, it may be sent 231 to an RCD 60, 126 a-b for processing. The RCD 60, 126 a-b may process 232 the data and determine whether the job complies with concurrent user account restrictions as described above. When this determination has been made and the concurrent account user receives accounting approval, the IDev 120, 30 a-30 d may prompt 232 b for job configuration data from a user. This job configuration data may be received as described above. Once this job configuration data is received, it may be sent 233 to an RCD 60, 126 a-b for processing. When concurrent user parameters are not met, the job may be denied 232 a.

As in some other embodiments, an accounting application running on the RCD 60, 126 a-b may then calculate 234 job costs, fees or charges from the job configuration data. Once costs, fees or charges are calculated for the job, they may then be compared 235 by the accounting application with accounting restrictions and an account verification process may be employed as described above. When this determination has been made and the job configuration receives accounting approval, the job costs, fees or charges may be applied 235 b to the user account. The IDev 120, 30 a-30 d may then execute the job 236 as configured. In some embodiments, if the job configuration does not receive accounting approval, the job request may be denied 235 a.

In some embodiments, the IDev, 120, 30 a-30 d may send 237 job results to an RCD 60, 126 a-b for processing. An accounting application running on the RCD 60, 126 a-b may then determine if the job was completed successfully and within accounting parameters. If the job was not completed successfully or if an accounting parameter exceeded its limits, the application may adjust 238 the costs, fees or charges applied to the user's account. The process may continue 239 without further adjustment when the job is completed successfully and within accounting parameter limits.

Some embodiments of the present invention may be described with reference to FIGS. 10, 12, 24A & 24B. These embodiments comprise an IDev 120, 30 a-30 d that is capable of receiving 240 account ID data from a user as described above in relation to other embodiments. Once this account ID data is received 240, it may be sent 241 to an RCD 60, 126 a-b for processing. The RCD 60, 126 a-b may process 242 the data and determine whether the job complies with concurrent user account restrictions as described above. When this determination has been made and the concurrent account user receives accounting approval, the IDev 120, 30 a-30 d may prompt 242 b for job configuration data from a user. This job configuration data may be received as described above. Once this job configuration data is received, it may be sent 243 to an RCD 60, 126 a-b for processing. When concurrent user parameters are not met, the job may be denied 242 a and further processing may cease.

As in some other embodiments, an accounting application running on the RCD 60, 126 a-b may then calculate 244 job costs, fees or charges from the job configuration data. Once costs, fees or charges are calculated for the job, they may then be compared 245 by the accounting application with accounting restrictions and an account verification process may be employed as described above. When this determination has been made and the job configuration receives accounting approval, the job costs, fees or charges may be applied 245 b to the user account. The IDev 120, 30 a-30 d may then execute the job 246 as configured.

In some embodiments, if the job configuration does not receive accounting approval, the job request may be automatically reconfigured 245 a to a configuration that meets accounting restrictions and sent to the IDev 120, 30 a-30 d for execution.

In some embodiments, the IDev, 120, 30 a-30 d may send 247 job results to an RCD 60, 126 a-b for processing. An accounting application running on the RCD 60, 126 a-b may then determine if the job was completed successfully and within accounting parameters. If the job was not completed successfully or if an accounting parameter exceeded its limits, the application may adjust 248 the costs, fees or charges applied to the user's account. The process may continue 249 without further adjustment when the job is completed successfully and within accounting parameter limits.

Some embodiments of the present invention may be described with reference to FIGS. 10, 12, 25A & 25B. These embodiments comprise an IDev 120, 30 a-30 d that is capable of receiving 250 account ID data from a user as described above in relation to other embodiments. Once this account ID data is received 250, it may be sent 251 to an RCD 60, 126 a-b for processing. The RCD 60, 126 a-b may process 252 the data and determine whether the job complies with concurrent user account restrictions as described above. When this determination has been made and the concurrent account user receives accounting approval, the IDev 120, 30 a-30 d may prompt 252 b for job configuration data from a user. This job configuration data may be received as described above. Once this job configuration data is received, it may be sent 253 to an RCD 60, 126 a-b for processing.

A method for enabling use of an imaging device account by multiple concurrent users, said method comprising: receiving, at a remote computing device (RCD), a user account identification (ID) from an imaging device for an imaging device account; receiving job configuration data for an imaging job at said RCD from said imaging device; calculating initial job charges at said RCD using said job configuration data; determining a job charge accuracy based on whether said job charges are accurately predicted; determining a concurrent user limit for said imaging device account based on said job charge accuracy and the accuracy of any pending jobs for said imaging device account; determining whether said concurrent user limit will be exceeded by approving said imaging job; automatically modifying said job configuration to meet accounting restrictions when said job charges do not meet accounting restrictions. if said concurrent user limit will be exceeded by said imaging job: denying further imaging device account access; if said concurrent user limit will not be exceeded by said imaging job: verifying that said initial job charges meet accounting restrictions for said account; applying said initial job charges to said account prior to authorization of said job when said initial job charges meet said accounting restrictions; authorizing said imaging device to execute said job when said initial job charges meet said accounting restrictions; providing for modification of said job when said job charges do not meet said accounting restrictions; recalculating said job charges based on said modification when said job charges do not meet said accounting restrictions; applying said modified job charges to said account when said initial job charges do not meet said accounting restrictions; and sending said modified job to said imaging device for execution on said imaging device.
 10. A method as described in claim 9 wherein said providing for modification of said job comprises prompting a user to modify said job configuration when said job charges do not meet accounting restrictions.
 11. A method as described in claim 9 further comprising determining whether said job was completed successfully and adjusting said job charges applied to said account to account for any unsuccessful job completion.
 12. A method as described in claim 9 further comprising determining whether said job charges are accurate based on data obtained after commencement of job execution and adjusting said job charges applied to said account to account for any inaccuracy in the initial calculation of said job charges.
